PICK.

Specification of Letters Patent.

Application filed April 1, 1908.

Patented Oct. 27, 1908.

Serial No. 424,641.

To all whom it 'may concern:

Be it 'known that I, ADoLPi-I OSTLUND, a citizen of the United States, residing at EX- line, in the county of Appanoose and State of Iowa, have invented certain new and useful Improvements in Picks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to means for fastening a pick to a handle, and has for its obj ect, the provision of means for facilitating the fastening of an ordinary pick, to, preferably, a wooden handle, whereby the pick can be quickly detached, when desired.

Another Object of the invention is the provision of peculiarly-constructed means for quickly attaching a pick to a handle or allowing said pick to be quickly detached therefrom.

\Vith these and other objects in view, the invention consists of certai n novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings: Figure 1 is a fragmentary, top plan view of a pick, having assembled therewith, a deviee constructed' in accordance with the present invention. Fig. 2 is a fragmentary view, partly in section, of a pick and a handle, and showing the fastening means, whereby the pick is detachably secured to said handle. Fig. 3 is a perspective view of one of the dogs. Fig. 4; is a fragmentary, perspective view of the casing. Fig. 5 is a fragmentary view, in elevaton, of one of the Sections of the casmg.

Fig. 6 is a perspective view of the drift-kcy. Referring to the drawings by numerals, 1 designates the pick and 2 is the handle. The pick is provided with an elongated Opening 3 formed in the center or body portion t, and said Opening terminates at its outer or upper end in outwardly-curved walls 5, which are formed, at opposite ends, of the elongated Opening or aperture 3, Fig. 2.

The casing surrounding the inner end of the handle, comprises, preferably, a pair of Sections. When the Sections are secured together, they produce a body 6, that surrounds the inner end of the handle, Fig. 2. Each section is provided, with a side 7 and an enlarged inner body portion, which is provided with a slit or bifurcated portion 8. The bifurcated portions 8 form an opening 9, Fig. 2, into which the drift-key 10 may be inserted for removing the wedge 11,

which constitutes fastening means for holding the dogs 12 in their locked position upon the pick l, as hereinafter described. The sections of the casing 6 are secured together by fastening means 13', extending through the sides of the sections of the easing, and also through the cylindrical body portion of the dogs 12; the cylindrical body portion being formed integral with the lower end of the body of the dog, said lower end of the body producing an outwardly-bulged portion, as at 13, which bears against one of the sockets 14: of the section. Each section of the casing is provided with-a pair of sockets 14, for as there is a pair of dogs 12 employcd in constructing my device, the sections must be provided with a pair of sockets 14, which sockets on each section register with the sockets on the other section, thereby producing a pair of soekets in the casing 6 engaged by the lower beveled portions'of the pockets, Fig. 2. Eaeh dog 12 is provided with a` cnrved, upper face 15, producing an outwardly extending lip 16; the Curved' outer faces 15 conforming to the contour or shape of the curved ends 5 of the pick 1.

Each section of the casing is provided with an integral, tapering wedge 16', upon its inner face, contiguous to the bifurcated portion or Opening? 8, Fig. 5, which slightly ipenetrates or splits the inner end of the handle for assisting in securing the handle within the casing 6; to further assist in secaring the handle .in said casing, I, preferably, insert or force a wedge 17 down into the' inner end of the handle 2, prior to the insertion of the wedge 11, so that the handle 2 will be fiXedly secured within the handle G, against accidental displacement.

To assemble my device, the sections of the casing are brought together, and then the dogs are inserted in the sockets 14 of the casing, and fastening means 13', as for instance, pins or rivets, is then forced through the sections of the casing and through the dogs to hold the same together. However, said fastening means permit the dogs to have pivotal movement upon the casing. The handle 2 isthen inserted into the casing in engagement with the small integral wedges 16' on the casing, and, subsequently, the detachable wedge 17 is forced into the inserted end of the handle. The dogs 12 are then pivoted together, as shown by dptted lines 18, Fig. 2, and the pick 1 placed upon the end of the casing and over the dogs 12. hen the pick is so positioned, Fig. 2, the dogs are swung apart, and the fastening wedge or key 11 is inserted and driven down between the dogs for securely holding the same in engagement with the opposite ends of the elongated Opening or apcrture 3, Figs. l and 2. When it is desired to remove the pick off of the casing and the handle, all that is necessary is to insert the small end of the drift-key 10 in the transverse Opening 9 of the casing below the fastening-key or wedge 11, and as said drift-key increases in width towards one end, and as the smallest end is inserted first, it will readily be seen that as the driftkey is driven through the Opening, the detachable and slidable fastening key 11 will be forced outward, and quickly removed and the dogs pivoted together for permitting the pick to be removed off of the handle.

hen the dogs are spread apart within the handle 1, as shown in Fig. 2, and the fastening means 11 is placed between said dogs, owing' to the outwardly-extending portions at their ends (to wit: the outwardlybulged portion 13 and the outwardly-extending lips or spurs 16) any strain upon the handle or casing or upon the pick will be distributed upon the two different parts of each dog and the two different parts of.

the casing and pick, so that a very durable fastening device is produced in ny structure, which is not only simple in construction, but owing to its simplicity can be quickly operated for either attaching or detaching the handle of the pick. If it is desired, the fastening means 13 can be entirely removed ofl? of the casing, and the dogs detached from the casing, and by reason of this structure, a new dog may be inserted, if one should become destroyed', without destroying the utility of the whole structure or involving the expense of an entirely new fastening device, which is an important advantage in the construction and maintenance of an operative device.

It is to be noted that the handle 2 is prevented from being forced too far into the sectional casing, by reason of the shoulders 19, Fig. 2, for ,the inner end oi" said handle abuts against these shoulders and limits the inward sliding movement prior to said handle being positively fastened therein against displacement by inserting the removable wedge 17, although the small fixed wedges 16 of the casing will materially assist in fastening the handle within the casing.

What I clai'm is:

1. In a device of the character described, the combination with a casing, a pick engaging said casing, of a pair of pivotally mounted dogs carried by said casing and extending into said pick, and means positioned between said dogs and normally holding the same apart for causing the same to engage opposite portions of the pick and thereby hold the pick and casing together.

2. In a device of the character described, the combination with a casing, of pivotally mounted dogs positioned in said casing and extending beyond one portion thereof, a pick surrounding parts of said dogs, and a locking-key positioned between said dogs and adapted to cause the same to engage opposite portions of the pick for securing said pick to the casing.

The combination with a casing and a pick engaging the same, of a dog extending into said casing and pick, said dog provided near one end with an outwardly-extending flange or integral portion, and at its opposite end, with an outwardly bulged portion,

means for holding said outwardly bulged' portion in engagement with the casing and said fiange in engagement with the pick, whereby said pick is normally secured to said casing.

4:. In a device of the character described, the combination of a casing provided with a transverse Opening, a pick engaging said casing, separable fastening means positioned in the casing and said pick, and means positioned contiguous to the Opening or" the casing and adapted to hold said separable fastening means in engagement with the pick for securing said pick to the casing, said Opening being adapted to receive a member for releasing or detaehing said fastening means for permitting the pick to be' removed *from said casing.

5. In a device of the character described, the combination of a casing, dogs positioned in said casing and extending beyond one end thereof, each dog provided with a body portion having at its inner end a cylindricalportion engaging. the casing and at its outer end an outwardly-extending spur or flange, a pick having an Opening, the dogs extending into said Opening of the pick, the opening of the pick provided with opposite portions conforming to the shape of the body of the dogs and their flanges or spurs, and a tapering wedge-shaped fastening member positioned between said dogs and adapted to hold the same in a locked position for securing the pick to the casing.

In testimony whereof Ihereunto aflix my signature in presence of two witnesses.
